` Patented Dec. 6, 1932 f fr Y l. AN,TISKliniinve-nmrren v rThe present invention relatesto `an :antskiddifngdevic'e for automobile tires, and Ihas for an objectto practically eliminate the great hazard; of ASkdding and B'Slppng :on

'5 slippery roadways occasioned `by ice, snow,

Y mudaslnieiand the like! l Another'object is' to provide an anti-skid attachment-constructed for application to balloon tires so as `not to restrict the free i0 flexing of the same, and to obtain the beneiit of the full width of thetread of the balloon tire, and at the same time to provide relatively rigid cross tread members for supporting calks or spurs adapted to engage in ythe ice,

i 15 mud or the like. y

A further object of the invention is to provide an anti-skidding device Vwith a plurality of rigid cross members and a flexible connecting band for holding the cross members in deiinite spaced apart relation and from creeping and chafing the tire vthe band also maintaining the structure from en tanglement when removed from the tire` and stored away, so that the device may be quickly and easily' applied for use.

With the foregoing and other objectsv in view,"the invention will be more fully described hereinafter, and will be more particularly pointed out A in the Vclaim' appended hereto. y
